Physical effects of cocaine

Each of the three forms of cocaine produces an intense ‘rush’, with the purity and the amount of the drug taken determining its intensity. Users feel a sense of euphoria, alertness, arousal, and increased confidence. All three forms suppress appetite.

When using cocaine, the rush experienced is actually the receptors in the brain being flooded with a neuro-chemical called dopamine. Because cocaine is tapping into the brain’s ‘reward system’, users begin to crave more of it to experience the same pleasure again. This is the reason many users find the drug to be so addictive.
